SPECIFICATION forming part of Letters Patent No. 709,841, datedSeptember 23, 1902.

Application filed May 20, 1902.

.To all whom t may concern:

Be it known that I, LoUIs N. D. WILLIAMS,

a citizen of the United States, residing in Ashbourne, Montgomerycounty, Pennsylvania, have invented certain Improvements inKnitting-Machines, of which the following is a specification.

My invention relates to that class of knitting-machines in which theneedle-operating cams are secured to or formed on removable cam-carriersor segments thereof, the object of my invention being to provide meanswhereby the needles of the needle-carrier, if deranged during or afterthe removal of the cam-carrier or segment thereof, may be readilyrestored to their proper position, so as not to interfere with thereplacing of said camcarrier or segment. This object I attain in themanner hereinafter set forth, reference being had to the accompanyingdrawings, in whichf Figure 1 represents a sectional view of theneedle-dial and dial cam-carrier of a rib-knitting machine with myinvention appliedy thereto, the dial cam-carrier being shown in theelevated position in order to permit inspection, removal, or repairingof its cams. Fig. 2 is a similar view showing the dial camcarrier inoperative relation. with the dial and its needles, and Fig. 3 is a planview showing the' cams of the dial cam-carrier and that element of themachine which constitutes the subject of my invention in operativerelation therewith.

In the operation of knitting-machines it is desirable to obtain accessto all portions of the needle-carrier in which the needles reciprocate,and this has led to the construction of machines with cam-carriers whichcan be moved bodily or, in some cases, in segments, so as to permit suchaccess to the needle-carrier; but the objection to this class ofmachines is that during the time that the camcarrier or segment thereofis being removed or afterward the needles in the corresponding portionof the needle-carrier are liable to become deranged to such an extent asto prevent the restoration of the cam-carrier or segment thereof,because of the fact that the butts of the needles are not in line withthe grooved cam-path which normally receives Serial No. 108,187. (Nomodel.)

the same. With the view of overcoming this objection I provide theneedle-carrier with a templet having a conformation substantiallysimilar to that of the inner or lower portion of the cam which acts uponthe butts of the needles, this templet being intended to serve as a stopfor the inner ends of the needle- Shanks-or other available portion ofthe needle, so that .when all of the needles are in con- 6e tacttherewith their butts will be in proper position to register with thecam-path of the cam-carrier and will not therefore interfere with theready readjustment of the cam-carrier or segment thereof after it hasbeen removed from the machine or so adj usted thereon as to permitaccess to its cams.

In the drawings I have illustrated my invention as applied to aneedle-dial, such as is employed in a rib-knitting machine; but it 7owill be evident' that my invention is not limited to such use, but canbe employed in connection with the needle-cylinder or otherneedle-carrier of the machine with like advantage.

In the drawings, l represents the needledial; 2, the needles of the samehaving projecting butts 3, and 4 represents the dial cam-plate which hasthe needle actuating cams secured to the under face of the same, 8o thisdial cam-plate being movable vertically on the central post or stem 5,which supports the dial, a pin 6, parallel with said stem, serving toprevent any rotative movement of the dial cam-plate on the stem, whilepermitting free vertical movement of the same.

The templet is represented at 7, said templet being secured to the upperface of the dial and having an outer conformation substantially similarto that of the inner cams 9o of the dial cam-plate, each set of camscomprising in the present instance a fixed projecting cam 9, a swingingprojecting cam 10, an inner guard-cam ll, an outer`draw-in cam 12, andan outer guard-cam 13.

When the inner ends of the stems of the needles are in contactwith theouter face of the templet and the swinging cams l0 are retracted, thebutts 3 of the needles will properly register with the cam-pathpresented by roe the cams. Hence the dial cam-plate can be dropped downonto the dial without any interference arising from the projecting buttsof the needles.

Having thus described my invention, I claim and desire to secure byLetters Patentl. The combination of the needle-carrier and cam-carrierof a knitting-machine, with a templet whereby the needles may beadjusted to such position that their butts will register with thecam-path of the cam-carrier or segment thereof which normally receivessaid butts, substantially as specified.
